' Application filed January 27, 1e22, serial No. 532,203. Renewed January 6, 1922.

To all whom it'may concern: 1 Be it known that 1, JOHN P. KIN a citizen of the United States, residing at 'Providence, in the county of Providence and State of Rhode Island, haveinvented certain new and useful Improvements in Braiding Machines, of. which the following is a specification. i r This invention relates to improvements in braiding machines for-braiding cords, fab-- rics, and the like, and has for one of its objects to provide an improved braiding machine c able rate ofspeed.

Another objectof the invention is to it;

v'ide an improved machine wherein the lines of travel 'ofthe carrier are straight from one point to another thus reducing the triotion. and lessening the wear on the running parts giving greater durability and materially reducing the c'ostof repairs. -h

A further object of the invention is provision :of cooperating means in the ear- {rier and the walls of the raceway whereby the carrier is ravelin portion of the racewa "With' these and other-objects in of construction, as will" be more fully described, and particularly pointed out in the appended clanns. p

In the accompanying'drawings:

, 2-2 of Figure 1. s Figure 3 is a view showing the circular of the carrier in section on line 3.3 of

of the inner .wall of the raceway web portion of thecarrier-shoe. a

Figure 4' is-a sectional elevation 011151 w th the construction of the inner wall of the raceway at the curve, with the web of rier-shoe. Q 7 l Figure 5 is. aside elevation' illustrating the undercut circular portion of the'quoit also illustratin the bearing post as formed in v 1 withvt is quoit. v i

I vFigure 6 is a perspective view of the web portion of thecarrrer with the top flange of running at a very high e portions interlock one with the other while g about the circularview, the inventlon conslstsof certam novel features plished portion'of the raceway and showing the web H of Figure 3 Showing the interlocking the car-Q removed showing the combined straigh and recessedportion of the inner face of the web.

It is found in practice of advantage in the running of high-speed braiding machines, to keep the carriers moving in as nea lastra-ight 'line as possiblewhile traveling back and forth across the track plate on oppdsite sides of the braiding center, and it portion of the. bobbin-carrier which runs in the raceway, the maximum bearing surface, to extend itswearing life, and to accomplish this" in ajsimple and effective way is also found of advantage to provide that I have lpirovided the web-portion of the car-r end bearing portions with straight bearing side walls to guide the carrier through the straight portions of the raceway, and in order to maintain a uniform width of race way both on the straightand curved por- I tionsI have undercut a portion of the curved side wall'of the raceway quoit and I have also recessed-a portion of the side wall of that of the carrier web, andthe following is .thebearing web whereby a portion oftheraceway wall isradapted to interlock with a detaileil description of one constructionby, which these results may be accom- With. ference to the drawings, 10 des-' ignates the bottom. plate of myimproved braiding machine which is provided with lugs. 11 by which it isbolted to any suitable support, and spaced a suitable distance above this bottom plate .is the to or track plate 12 being held securely in t is spaced :relatihn by four shouldered studs 13'. Figure 4 to illustrate the interlocking effect able openings into which quoit plates 14 are set coo eratin ,Th-is'track plate 12 is provided with suitwith :the openings in the ate to 01m two sets of racew'ays 15 to guide the travel of two difierent carriers (not shown). These quoit track and 1? sets 0 inc Iplates, inthis particular style of machines,

, each provided with an integral stud 17 having a bearing portion 18, ;for the driva binding bolt 22f This lower portion is re duced in diameter beyond that of the bearing portion '18, and its shoulder 23 by resting upon-the boss 24: accurately regulates the height of the quoit plate in thetrackplate also this reduced portion 21 ispro: vided with a .key 2-5 which serves to accurately position the quoit plate circularly in the track-plate.

The outer port1on26 of each of these quoit plates is rounded to cooperate with the correspondingly rounded portion 27 of the track-plate and a portionof this curved ing adapted to cooperate withthe adjacent opposite edge of the end quoits thereby providing straight line raceways across the track-plate crossing each other at substantially 90 angles. In order to provide bobbin carriers for these raceways I have constructed a carrier with a bodyor shoe portion having upper and lower flanges 31 and 32 connected by a} web 38 which web, as'illustrated in Figure 3, is provided with rounded or curved end a bearing portions 34: adapted to engage the outer and innerstraight side walls 35 and- 36, the inner side wall being preferably grooved as at 37 'for a portion of its width outer surface 2'7 of the raceway when pass ing around the curvesfat the ends of the racewayand the web connecting these curved'end portionsis provided with both to receive the overhanging portion 26 of the outer circular edge of the quoit plate thereby providing a bearing surface 38 which cooperates with those of the overhanging carrier in a vertical position while being driven rapidly about the circular portion of the raceway and by this construction it will be seen that although the inner face of this web portion is recessed, stlll a large section of the straight portion of the web remains for guiding the carrier while passing along the straight portion of the raceway'thereb'y obtaining the maximum bearing surface both.

for supporting the carrier when traveling in the curve as wellas in the straight portions of the raceway, and'by my improved construction of obtaining large-bearing areas in the carrier and straight line runs in the raceways a very high running speed may be obtained, the working life of the machine is greatly extended and a high quality of work is produced.

The foregoing description is directed solelyto-wards the construct-ion illustrated, but I desire it to be understood that I re;

. quoit."

serve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the termsof the appended claims. I V
